Patients will be divided into 2 groups, based on objective activity duration: 'low-activity' and 'high-activity'. The threshold will be the median of the total population. HbA1c, blood pressure, quality of life, biological results and general characteristics will be compared between the 2 groups with a Student test or a Mann-Whitney test, depending on the normality of distribution. Qualitative variables will be studied with a chi-square test.
